Description

Technical Field

[0001] This application relates to the technical field of imaging equipment, and more particularly to an imaging device and an optical inspection device. Background Technology

[0002] In the field of modern imaging technology, the stability and accuracy of imaging devices are crucial for acquiring high-quality detection data. However, when imaging devices need to be transported or used in dynamic environments with frequent acceleration and deceleration, their stability and accuracy face severe challenges. Because many key components in imaging devices, such as cameras and lenses, are not designed with sufficient consideration for the impact of transportation and frequent acceleration and deceleration, this leads to limitations when used in complex or turbulent environments.

[0003] During transportation, imaging devices may be subjected to various forms of external impact, such as bumps and vibrations. If critical components such as cameras and lenses lack shock-resistant design, these impacts may cause loosening or slippage between internal stitching parts, and may also cause positional changes in core components, thereby affecting image quality and the accuracy of detection data. Especially when the precision required between these parts is high, even slight displacements can have a significant impact on the stability of the imaging system. Utility Model Content

[0004] The purpose of this application is to provide an imaging device that greatly improves the shock and impact resistance of the first camera component, ensuring that the installation position of the first camera component will not shift under impact, thereby improving imaging stability and accuracy.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] On one hand, an imaging device is provided, comprising: a frame, a first camera assembly, a fixing member, and a clamping member. The frame has a receiving space, and the first camera assembly is at least partially located in the receiving space. The fixing member is installed on the frame and has a fixing position that cooperates with and fixes the middle section of the lens of the first camera assembly. The clamping member is installed on the frame and can clamp the front end of the lens of the first camera assembly. Through the cooperation of the fixing member and the clamping member, the first camera assembly can be stably locked in the frame. In the event of significant vibration or impact, the relative position between the first camera assembly and the frame can be guaranteed not to shift, thereby ensuring the imaging effect of the first camera assembly.

[0007] Furthermore, the fixing component includes a fixing beam and a fixing ring. The fixing beam is connected to the frame and extends towards the receiving space to form a fixing part. The fixing ring is installed on the side of the fixing part away from the fixing beam. The fixing position formed between the fixing ring and the fixing part clamps the middle section of the lens of the first camera assembly. The fixing beam is stably connected to the frame, and the fixing beam and the fixing part are integrally formed, so the structural strength between them is sufficiently large. By clamping the middle section of the lens of the first camera assembly with the fixing part and the fixing ring, the lens is fixed from at least two positions, thereby improving the installation stability of the lens.

[0008] Furthermore, the clamping component includes a first clamping block and a second clamping block, both of which are mounted on the frame. The first and second clamping blocks cooperate to clamp the front end of the lens of the first camera assembly, and the first clamping block can be locked in place with the second clamping block. Both the first and second clamping blocks are fixed to the frame, and the locking mechanism between them effectively holds the front end of the lens, resulting in stronger compatibility and higher stability.

[0009] Furthermore, a mounting base is provided on the side of the frame, and a side imaging component is mounted on the mounting base. The side imaging component is either a projection component or a second camera component. The mounting base allows the side imaging component to be stably mounted on the side of the frame, ensuring the stability of the side imaging component installation.

[0010] Furthermore, the mounting base includes a horizontal portion, a vertical portion, and an inclined portion. The horizontal portion has a first locking hole for connection with the frame, and the vertical portion has a second locking hole for connection with the frame. The side imaging component is mounted on the inclined portion. The horizontal, vertical, and inclined portions are integrally formed. The first locking hole connects to the frame in the vertical direction, and the second locking hole connects to the frame in the horizontal direction. This connection and fixation in at least two directions ensures that the projection component does not undergo relative displacement within a certain impact range, significantly improving the shock resistance of the projection component.

[0011] Furthermore, a first reinforcing member is provided between the horizontal part and the vertical part, and a second reinforcing member is provided between the horizontal part and the inclined part. The vertical part and the horizontal part are vertically connected, and the inclined part and the horizontal part are inclinedly connected, that is, there is a certain angle between each pair. By providing the first and second reinforcing members, the structural strength of the mounting base can be significantly improved, thereby ensuring the shock resistance of the projection assembly.

[0012] Furthermore, the frame is provided with positioning components, and the mounting base is provided with positioning parts that cooperate with the positioning components for positioning. The positioning components and positioning parts work together to ensure the accuracy of the mounting base installation, thereby guaranteeing the precise installation of the projection component.

[0013] Furthermore, the side imaging assembly includes an outer lens barrel, a projection endoscope, and a clamp. The projection endoscope is threadedly connected to the outer lens barrel, and the clamp is located at the front end of the outer lens barrel and engages with the contact surface of the projection endoscope for locking.

[0014] Furthermore, the first camera assembly includes a camera body, a lens, and an adjustment ring. The adjustment ring connects the camera body and the lens and is used to adjust the back focal length of the camera body and the lens. The camera body is connected to the frame via a fixing plate. When there is an error in the front working distance of the lens, the adjustment ring can be adjusted to move the camera body, changing the back focal length and thus adjusting the image sharpness. At the same time, the fixing plate stably connects the camera body and the frame. Since the front, middle, and rear of the first camera assembly are connected to the frame via corresponding structural components, the stability between the first camera assembly and the frame is very high, and the probability of relative misalignment is extremely small.

[0015] Furthermore, the fixing plate is provided with waist holes, and the frame is provided with multiple fixing holes. After the fixing plate rotates relative to the frame, it is locked into the corresponding fixing hole by fasteners passing through the waist holes, thereby adjusting the relative angle between the camera body and the frame. The relative angle of the camera body can be controlled by adjusting the fixing plate to rotate it relative to the frame, thus controlling the image stitching.

[0016] On the other hand, an optical inspection device is also provided, characterized in that the optical inspection device includes an imaging device, a driving device, and a moving device as described above, the imaging device is disposed on the moving device, and the moving device drives the imaging device to move under the drive of the driving device.

[0017] The beneficial effects of this application are as follows: The imaging device mainly consists of a frame, a first camera assembly, a fixing component, and a clamping component. The frame, as the foundation of the entire device, is designed with a space to accommodate the first camera assembly. The structural strength and rigidity of the frame are sufficient to withstand external impacts and vibrations. The first camera assembly, as the core of the imaging process, is stably mounted within the frame using at least two fixing methods. The fixing component is stably connected to the frame and has a fixing position that matches the middle section of the lens of the first camera assembly, ensuring that the first camera assembly will not shift due to vibration or impact in the horizontal and vertical directions. The clamping component is also stably connected to the frame and is designed to clamp the front end of the lens of the first camera assembly. By providing sufficient clamping force, it further restricts the axial movement of the first camera assembly, effectively preventing the lens from loosening or shifting due to vibration. When the imaging device faces external impacts or vibrations, the fixing component and the clamping component work together to form a robust protective mechanism, firmly locking the first camera assembly within the frame. This dual-fixation mechanism not only improves the shock and vibration resistance of the first camera assembly, but also ensures the stability and accuracy of the imaging system, enabling the acquisition of high-quality detection data even in complex or turbulent environments.

Detailed Implementation

[0034] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the field of Automated Optical Inspection (AOI), the performance of the imaging device is crucial to inspection accuracy and efficiency. AOI imaging devices are widely used in various industries such as electronics manufacturing, semiconductor packaging, and PCB inspection for high-precision visual inspection of products. However, traditional AOI imaging devices often face challenges in design and use, especially in complex and variable industrial environments.

[0038] Traditional AOI imaging devices mostly use simple brackets or mounts to install camera components. These devices may perform well in static or slightly vibrating environments, but when subjected to greater vibrations or impacts, the camera components are prone to displacement, leading to decreased image quality and even detection errors. Displacement not only affects image clarity but also alters the camera's field of view, making the detection results inaccurate and unreliable.

[0039] To address this issue, a more robust imaging device was needed to ensure the stability and imaging quality of the camera components in complex environments. Initially, this presented a challenge: a fundamental shift in design philosophy. While traditional fixing methods were simple, they proved inadequate in the face of strong vibrations and high-impact environments. We understood that designing a completely new fixing system required breaking free from traditional frameworks and seeking innovative solutions. This demanded not only a deep understanding of the working principles and stress conditions of the camera components but also a strong foundation in materials science, mechanics, and other related fields.

[0040] Based on the above requirements, an imaging device is provided, such as... Figures 1-3 As shown, it includes: a frame 1, a first camera assembly 2, a fixing member 3, and a clamping member 4. The frame 1 has a receiving space, and the first camera assembly 2 is at least partially located in the receiving space. The fixing member 3 is installed on the frame 1 and has a fixing position 301 that cooperates with and fixes the middle section of the lens 202 of the first camera assembly 2. The clamping member 4 is installed on the frame 1 and can clamp the front end of the lens 202 of the first camera assembly 2.

[0041] The design of this imaging device revolves around improving the shock and vibration resistance of the first camera assembly 2. Firstly, the frame 1, as the foundation structure of the entire device, provides a stable support environment, and its internal space provides the mounting position for the first camera assembly 2. The design of the frame 1 must consider sufficient strength and rigidity to resist external impacts and vibrations. The first camera assembly 2 is the core component of the imaging device. To improve the stability of the first camera assembly 2, two fixing methods are adopted: a fixing member 3 and a clamping member 4. The fixing member 3 is mounted on the frame 1 and has a fixing position 301 that cooperates with and fixes the middle section of the lens 202 of the first camera assembly 2. The fixing position 301 is used to firmly fix the middle section of the lens 202 within the frame 1. The design of the fixing member 3 ensures the stability of the first camera assembly 2 in both horizontal and vertical directions, preventing horizontal or vertical displacement caused by vibration or impact. The clamping member 4 is also mounted on the frame 1, but its main function is to provide sufficient clamping force to clamp the front end of the lens 202 of the first camera assembly 2. When the front end of lens 202 is clamped, it further restricts the range of movement of the first camera assembly 2 under impact or vibration, especially in the axial direction of lens 202. This design helps prevent lens 202 from loosening or shifting due to vibration, thereby maintaining the stability and accuracy of the imaging system.

[0042] When the imaging device is subjected to external impact or vibration, the fixing member 3 and the clamping member 4 work together to stably lock the first camera assembly 2 within the frame 1. The fixing member 3 ensures the stability of the first camera assembly 2 in the horizontal and vertical directions, while the clamping member 4 prevents the lens 202 from moving in the axial direction. This dual fixing mechanism greatly improves the shock and impact resistance of the first camera assembly 2.

[0043] Overall, through the cooperation of the fixing component 3 and the clamping component 4, the first camera assembly 2 can remain stable when subjected to external impacts or vibrations, avoiding image quality degradation caused by displacement. The stable first camera assembly 2 ensures the stability and accuracy of the imaging system, enabling the acquisition of high-quality detection data even in complex or turbulent environments. Furthermore, the improved shock and vibration resistance extends the service life of the imaging device, reducing malfunctions and maintenance costs caused by vibration or impact. Moreover, this imaging device is suitable for various scenarios requiring transportation or use in dynamic environments with frequent acceleration and deceleration, improving its applicability and flexibility.

[0044] It should be specifically pointed out that, such as Figure 13 and Figure 14 As shown, the imaging device can be compatible with the installation of different first camera components 2 through the fixing part 3 and the clamping part 4, which can ensure the stability and shock resistance of the installation of different first camera components 2. Moreover, by replacing different first camera components 2, different detection accuracy and detection speed requirements can be met.

[0045] Furthermore, such as Figure 4As shown, the fixing member 3 includes a fixing beam 302 and a fixing ring 304. The fixing beam 302 is connected to the frame 1 and extends towards the receiving space to form a fixing part 303. The fixing ring 304 is installed on the side of the fixing part 303 away from the fixing beam 302. The fixing position 301 formed between the fixing ring 304 and the fixing part 303 clamps the middle section of the lens 202 of the first camera assembly 2. As a key component connecting the first camera assembly 2 and the frame 1, the fixing member 3 consists of two parts: the fixing beam 302 and the fixing ring 304. The fixing beam 302 first achieves a stable connection with the frame 1. Its design ensures that it can maintain a tight fit with the frame 1 in various usage environments, preventing displacement of the first camera assembly 2 due to loosening. The fixing beam 302 extends towards the receiving space to form a specific fixing part 303, which provides the necessary support for fixing the middle section of the lens 202. The retaining ring 304 is cleverly installed on the side of the fixing part 303 away from the fixing beam 302, forming a clamping space, namely the fixing position 301, together with the fixing part 303. The design of this fixing position 301 fully considers the shape and size of the middle section of the lens 202, ensuring a tight and stable clamping of the lens 202, thereby effectively preventing the lens 202 from shaking or shifting when subjected to external impacts or vibrations. Through the tight cooperation of the fixing part 303 and the retaining ring 304, the middle section of the lens 202 of the first camera assembly 2 is firmly clamped in the fixing position 301. With the clamping member 4 clamping the front end of the lens 202, stable fixation of the lens 202 is achieved from at least two positions. This design not only improves the installation stability of the lens 202 but also significantly enhances the overall shock and impact resistance of the first camera assembly 2, enabling the imaging device to maintain excellent imaging stability and accuracy in various complex or turbulent environments.

[0046] It is worth noting that the fixed beam 302 and the fixing part 303 adopt an integral molding design. This design not only simplifies the manufacturing process but also significantly improves the structural strength between the two. The integrally molded fixed beam 302 and fixing part 303 can jointly withstand the force when facing external impacts, effectively preventing the first camera assembly 2 from falling off or being damaged due to structural fracture.

[0047] Furthermore, such as Figure 5As shown, the clamping member 4 includes a first clamping block 401 and a second clamping block 402. Both the first clamping block 401 and the second clamping block 402 are mounted on the frame 1. The first clamping block 401 and the second clamping block 402 cooperate to clamp the front end of the lens 202 of the first camera assembly 2, and the first clamping block 401 can be locked in conjunction with the second clamping block 402. The design of the first clamping block 401 and the second clamping block 402 fully considers the shape and size of the front end of the lens 202, ensuring a tight fit and clamping of the front end of the lens 202, preventing it from shaking or shifting when subjected to external impacts or vibrations. Simultaneously, both the first clamping block 401 and the second clamping block 402 are designed for stable connection with the frame 1, ensuring their stability in various usage environments. A locking structure is designed between the first clamping block 401 and the second clamping block 402. This structure allows the clamping effect to be further consolidated through the locking mechanism after the two clamp the front end of the lens 202, ensuring that the front end of the lens 202 remains stable even under extreme conditions. This design not only improves the stability and reliability of the clamping component 4, but also enables the imaging device to maintain excellent imaging performance when facing complex or turbulent environments.

[0048] Furthermore, the mating locking structure of the first clamping block 401 and the second clamping block 402 provides the clamping member 4 with stronger compatibility. This means that regardless of the shape and size of the front end of the lens 202, stable clamping of different lenses 202 can be achieved by adjusting the design of the clamping blocks. This design enables the imaging device to be adapted to a wider variety of first camera components 2, improving its flexibility and versatility in practical applications.

[0049] The first clamping block 401 and the second clamping block 402 are both semi-circular in shape. This design not only conforms to the circular shape of the front end of the lens 202, but also provides uniform clamping force, ensuring that the lens 202 will not loosen or shift when subjected to external impact or vibration. The first clamping block 401 is locked to the bottom surface of the frame 1 by four fasteners (such as bolts or screws). These four fasteners are evenly distributed around the first clamping block 401, ensuring a stable connection between it and the frame 1. This not only improves the stability of the first clamping block 401, but also provides sufficient support when clamping the front end of the lens 202. The connection between the second clamping block 402 and the first clamping block 401 is locked by two fasteners. These two fasteners further consolidate the clamping effect and prevent the lens 202 from shaking or shifting when subjected to external forces. Meanwhile, the second clamping block 402 is also fixed to the bottom surface of the frame 1 by two screws. These two screws are located at the bottom of the second clamping block 402 and form a stable connection with the bottom surface of the frame 1. This design not only enhances the stability of the second clamping block 402, but also enables it to maintain better balance and stability when it is used in conjunction with the first clamping block 401 to clamp the front end of the lens 202.

[0050] In some embodiments, such as Figure 6 , Figure 7 As shown, a mounting base 5 is provided on the side of the frame 1, and a side imaging component 6 is provided on the mounting base 5. The mounting base 5, as a component connecting the frame 1 and the side imaging component 6, has a stable structure and reasonable design, which can perfectly adapt to the size and weight of the side imaging component 6, ensuring that the side imaging component 6 remains stable during long-term use and will not be displaced due to vibration or external force.

[0051] Specifically, the side imaging component 6 can be a projection component or a second camera component depending on different detection requirements. The specific structure of the mounting base 5 needs to be adapted to different side imaging components 6 to meet different installation requirements.

[0052] In the application of the imaging device to solder paste inspection, the side imaging component 6 is specifically a projection component. This component is mounted on the mounting base 5 on the side of the frame 1. This placement not only allows the projection component to easily project image information such as lines onto the product to be inspected, but also ensures that the projection light maintains a certain angle with the line of sight of the first camera component 2, thus avoiding interference from the projection light and improving the clarity and accuracy of the image. The projection component is highly functional; it can clearly project preset image information such as lines, patterns, or text onto the surface of the product to be inspected using high-precision projection technology. This function not only greatly enriches the application scenarios of the imaging device but also allows users to easily obtain image information from the product, and then, through image analysis technology, obtain precise image information of the product, such as key parameters like size, shape, and position.

[0053] Furthermore, the collaborative operation of the projection component and the first camera component 2 enables efficient product detection and precise positioning. During the detection process, the lines or patterns projected by the projection component can serve as a reference benchmark, helping the first camera component 2 to more accurately capture the product's feature information, thereby improving the accuracy and efficiency of the detection.

[0054] Specifically, such as Figure 8 As shown, the mounting base 5 includes a horizontal part 501, a vertical part 502, and an inclined part 503. The vertical part 502 is located on the upper side of the horizontal part 501, and the inclined part 503 is inclinedly located on the lower side of the horizontal part 501. The horizontal part 501 is provided with a first locking hole 5011 for connecting to the frame 1, and the vertical part 502 is provided with a second locking hole 5021 for connecting to the frame 1. The projection component is mounted on the mounting surface of the inclined part 503 on the side away from the frame 1.

[0055] In this design, the mounting base 5 is composed of three parts: a horizontal part 501, a vertical part 502, and an inclined part 503. These three parts are manufactured using an integrated molding technology, which ensures the stability and integrity of the structure.

[0056] The horizontal part 501 serves as the bottom support of the mounting base 5. Its design is flat and stable, and it can perfectly fit the bottom surface of the frame 1. A first locking hole 5011 for connecting with the frame 1 is specially provided on the horizontal part 501. This design allows the mounting base 5 to be firmly connected to the frame 1 in the vertical direction by bolts or other fasteners, thereby ensuring the vertical stability of the mounting base 5.

[0057] The vertical portion 502, serving as the main body of the mounting base 5, is perpendicular to the horizontal portion 501. A second locking hole 5021 for connection to the frame 1 is also provided on the vertical portion 502. This design allows the mounting base 5 to be further connected to the frame 1 in the horizontal direction using additional bolts or other fasteners. Through connection and fixation in at least two directions, the connection between the mounting base 5 and the frame 1 is more robust, thereby ensuring that the projection assembly will not experience relative displacement when subjected to impact or vibration.

[0058] The tilting portion 503, serving as the structure for mounting the projection assembly, is tilted below the horizontal portion 501, forming a 30° angle. This design not only allows the projection assembly to be mounted at a certain angle on the mounting surface of the tilting portion 503 away from the frame 1, but also ensures that the relative angle between the projection assembly and the frame 1 satisfies the Scherm principle. The Scherm principle is a widely used principle in the fields of photography and imaging. It requires that the various components (frame 1, projection assembly) in an imaging system maintain a specific angular relationship to ensure the sharpness and accuracy of the image. In the design of the mounting base 5, by precisely calculating and adjusting the angle between the horizontal portion 501 and the tilting portion 503, the requirements of the Scherm principle are successfully met, improving the sharpness and accuracy of the imaging device.

[0059] Furthermore, if sufficient installation space is left between the tilting part 503 and the frame 1 after the mounting base 5 is connected to the frame 1, the side of the tilting part 503 opposite to the frame 1 can also be designed as a mounting surface, and the projection component can be mounted on this mounting surface, thereby making the entire imaging device more compact and further reducing the space occupied in the horizontal direction. When both sides of the tilting part 503 are mounting surfaces, the projection component can be selected for installation according to actual design requirements.

[0060] It is important to note that there are two first locking holes 5011 for vertical connection with the frame 1. This design not only ensures the vertical stability of the mounting base 5 but also facilitates subsequent debugging and maintenance. Four second locking holes 5021 are arranged in an array on the vertical section 502, increasing the number of connection points between the mounting base 5 and the frame 1. This array arrangement also makes the connection more uniform and stable. When subjected to impact or vibration, these four second locking holes 5021 can share the force, effectively reducing the relative displacement between the mounting base 5 and the frame 1, and significantly improving the shock resistance of the projection assembly.

[0061] Furthermore, a first reinforcing member 504 is provided between the horizontal portion 501 and the vertical portion 502, and a second reinforcing member 505 is provided between the horizontal portion 501 and the inclined portion 503. The first reinforcing member 504, as a component connecting the horizontal portion 501 and the vertical portion 502, is designed with full consideration of the vertical connection relationship between the two parts. Through reasonable size and shape design, the first reinforcing member 504 can effectively distribute and bear the forces from the vertical portion 502 and the horizontal portion 501, thereby ensuring a more stable and reliable connection between the two. This not only improves the vertical stability of the mounting base 5 but also provides a more solid support for the projection assembly. The second reinforcing member 505 is located between the horizontal portion 501 and the inclined portion 503, and is used to strengthen the inclined connection between the two. Because there is a certain angle between the inclined portion 503 and the horizontal portion 501, the design of the second reinforcing member 505 needs to be more refined and complex. Through precise calculations and simulation analysis, a second reinforcing member 505 was designed that conforms to mechanical principles and meets practical application requirements. This improves the stability of the mounting base 5 in the tilting direction and further enhances its overall structural strength. Generally, the first reinforcing member 504 and the second reinforcing member 505 are integrally formed on the mounting base 5, ensuring that the overall structural strength of the mounting base 5 meets installation requirements.

[0062] In the design of frame 1, a positioning element 22 is cleverly incorporated. The positioning element 22 can be a raised positioning pin, a positioning hole, or other form of positioning structure, precisely positioned at a predetermined location on frame 1. The design of the positioning element 22 not only considers ease of installation but also fully considers the accuracy and stability of positioning. Simultaneously, a positioning part 5012 is correspondingly provided on the mounting base 5 to cooperate with the positioning element 22 for positioning. The positioning part 5012 can be a positioning hole matching a positioning pin or a positioning protrusion matching a positioning hole. Through precise calculation and simulation analysis, the fitting accuracy and stability between the positioning part 5012 and the positioning element 22 are ensured.

[0063] During installation, the initial positioning of the mounting base 5 can be achieved simply by aligning and inserting the positioning part 5012 on the mounting base 5 with the positioning member 22 on the frame 1. This design not only simplifies the installation process but also greatly improves the accuracy and efficiency of installation. More importantly, the positioning by the cooperation of the positioning member 22 and the positioning part 5012 ensures the accuracy of the mounting base 5 during installation. This accuracy is reflected not only in the relative position between the mounting base 5 and the frame 1 but also in the precise installation of the side imaging component 6 relative to the frame 1. Since the installation accuracy of the side imaging component 6 is crucial to the imaging quality, this cooperative positioning design is of great significance for ensuring the stability and accuracy of the imaging device. In addition, the cooperative positioning of the positioning member 22 and the positioning part 5012 also has a certain degree of fault tolerance. Even if there are certain errors or deviations during installation, the cooperation between the positioning member 22 and the positioning part 5012 can be corrected and adjusted to a certain extent, thereby ensuring the final installation accuracy and stability.

[0064] In the design of the imaging device, the stability and shock resistance of the side imaging assembly 6 are crucial. To further improve these properties, an innovative clamping solution 603 is adopted to replace the traditional five-screw clamping solution. While the traditional five-screw clamping solution can fix the projection endoscope 602 to a certain extent, it has several shortcomings. First, the contact area between the end face of the set screw and the projection endoscope 602 is small, resulting in insufficient friction and making it difficult to ensure the stability of the lens 202. Second, the anti-loosening ability between the set screw and the lens barrel is poor, making it prone to loosening during prolonged use or impact. These problems seriously affect the stability and shock resistance of the side imaging assembly 6.

[0065] To overcome these shortcomings, this solution adopts a clamping method using 603 clamps. In this solution, as... Figure 9 , Figure 10 As shown, the projection endoscope 602 is threadedly connected to the outer lens barrel 601, ensuring a tight fit between the projection endoscope 602 and the outer lens barrel 601. Simultaneously, a clamp 603 is provided at the front end of the outer lens barrel 601, which can tightly fit with the contact surface of the projection endoscope 602 and achieve locking. This clamping method increases the contact area between the projection endoscope 602 and the clamp 603, thereby improving friction, and the locking effect of the clamp 603 further enhances the stability of the connection. The clamp 603 includes two opposing semi-rings, which are locked together by two screws.

[0066] Furthermore, the outer lens barrel 601 is equipped with a threaded section for connecting to the projection endoscope 602, and a limiting end for restricting the installation position of the projection endoscope 602. A deformation groove is also specifically designed at the front end of the outer lens barrel 601. This deformation groove does not change the function of the threaded end and the limiting end, but rather provides better clamping space for the clamp 603. Through this clamping method, the outer lens barrel 601 and the projection endoscope 602 can be reliably connected, thereby greatly increasing impact resistance.

[0067] Furthermore, the first camera assembly 2 includes a camera body 201, a lens 202, and an adjustment ring 203. The adjustment ring 203 connects the camera body 201 and the lens 202 and is used to adjust the back focal length of the camera body 201 and the lens 202. The camera body 201 is connected to the frame 1 via a fixing plate 20. As a key component for imaging, the position and back focal length adjustment of the lens 202 directly affect the image sharpness. To achieve precise adjustment of the back focal length of the lens 202, an adjustment ring 203 is designed to connect the camera body 201 and the lens 202. The adjustment ring 203 not only securely connects the camera body 201 and the lens 202 but also allows adjustment of their relative position by rotation, thereby changing the back focal length of the lens 202. This adjustment method allows users to precisely adjust the back focal length of the lens 202 according to actual needs to ensure image sharpness.

[0068] Meanwhile, to enhance the stability between the first camera assembly 2 and the frame 1, a fixing plate 20 is used to connect the camera body 201 and the frame 1. The fixing plate 20 is designed to be robust and stable, effectively preventing the camera body 201 from shaking or shifting during imaging. Through the connection of the fixing plate 20, the stability between the first camera assembly 2 and the frame 1 is greatly improved, thereby ensuring the stability and accuracy of imaging.

[0069] It is worth noting that the fixed plate 20 has an adapter plate 21 inside that connects to the camera body 201. When the adjustment ring 203 is rotated, the adapter plate 21 and the camera body 201 will move up and down. At the same time, the adjustment ring 203 is equipped with a clamping screw. After the adjustment ring 203 is rotated, it is locked by the clamping screw to prevent accidental rotation.

[0070] Furthermore, the fixing plate 20 is provided with a waist hole 2001, and the frame 1 is provided with multiple fixing holes 101. After the fixing plate 20 rotates relative to the frame 1, it is locked into the corresponding fixing hole 101 by fasteners passing through the waist hole 2001, so as to adjust the relative angle between the camera body 201 and the frame 1. At least some of the fixing holes 101 are located within the vertical projection range of the waist hole 2001. The waist hole 2001 is cleverly provided on the fixing plate 20, which allows the fixing plate 20 to rotate relative to the frame 1 within a certain range. At the same time, the frame 1 is provided with multiple fixing holes 101, which are used to cooperate with fasteners to firmly lock the fixing plate 20 in a predetermined position.

[0071] When it is necessary to adjust the relative angle of the camera body 201, the fasteners can be loosened first, allowing the fixing plate 20 to rotate relative to the frame 1. Then, by rotating the fixing plate 20, the user can adjust the relative angle of the camera body 201 to meet different imaging needs. After adjustment, simply pass the fasteners through the waist holes 2001 and lock them into the corresponding fixing holes 101 to firmly fix the fixing plate 20 in the predetermined position, thereby ensuring the stability of the camera body 201 during the imaging process.

[0072] It is worth noting that the design of the waist hole 2001 allows the fixing plate 20 a certain degree of flexibility during rotation. Simultaneously, since at least some of the fixing holes 101 are located within the vertical projection range of the waist hole 2001, different fixing holes 101 can be selected for locking within a certain range, thereby further increasing the adjustment range of the relative angle of the camera body 201. By adjusting the fixing plate 20 to rotate the camera body 201 relative to the frame 1, the relative angle of the camera body 201 can be precisely controlled, thus achieving precise control of image stitching. This design not only improves the flexibility and adjustability of the imaging device but also provides users with a more convenient and reliable imaging solution.

[0073] In some embodiments, two supports 7 are symmetrically arranged at the bottom of the frame 1. A first light element 8 and a second light element 9 are vertically spaced between the two supports 7. The first light element 8 is fixed between the two supports 7 by a first connector 10, and the second light element 9 is fixed to the bottom of the two supports 7 by a second connector 11. The two supports 7 symmetrically arranged at the bottom of the frame 1 not only provide stable support for the two light elements but also ensure that the two light elements can distribute light evenly, reduce shadow areas, and improve the quality of the captured image. The supports 7 should be designed to be robust enough to withstand the weight of the two light elements and the possible vibrations, while maintaining sufficient flexibility for adjustment and maintenance. The first light element 8, fixed between the two supports 7 by the first connector 10, is located at a higher position and is mainly used to provide main lighting. The design of the first connector 10 should allow the first light element 8 to be adjusted within a certain range to achieve more precise lighting control. The second light element 9, fixed to the bottom of the two supports 7 by the second connector 11, is used as auxiliary lighting. The second light element 9 can be designed at a lower angle to illuminate the lower part of the subject or provide background lighting. Similar to the first light component 8, the second light component 9 should also have a certain angle adjustment capability.

[0074] Meanwhile, the frame 1 is also equipped with a connecting component, which can be connected to the outer shell 12 so that the outer shell 12 can cover the first light component 8, the second light component 9 and other structural components, achieving a full-coverage design. This not only protects the internal components but also makes the system look more integrated, while blocking the light source to prevent glare.

[0075] Among them, such as Figure 12 As shown, the connecting components include a first connecting plate 13 disposed at the bottom of the frame 1 and a second connecting plate 14 disposed on the upper side of the frame 1. The outer shell 12 includes a first shell 1201 and a second shell 1202. The first shell 1201 is connected to the frame 1 through the first connecting plate 13, and the second shell 1202 is connected to the frame 1 through the second connecting plate 14. The first shell 1201 and the second shell 1202 are spliced ​​together to form a fully enclosed outer shell 12. In addition, an adjustment block 19 is provided between the second connecting plate 14 and the frame 1, and the installation position of the second connecting plate 14 can be adjusted by adjusting the adjustment block 19. Furthermore, the outer shell 12 also includes a third shell 1203 that encloses the side imaging component 6. The third shell 1203 can be spliced ​​onto the first shell 1201 or the second shell 1202, or it can be integrally formed onto the first shell 1201 or the second shell 1202.

[0076] Generally, a backplate 15 is installed on the upper back of frame 1. A light source wiring board 16 and a cable chain 17 are mounted on the backplate 15, with a mounting plate 18 at the other end of the cable chain 17. The main function of the backplate 15 is to provide structural support, protect internal electronic components and wiring, and serve as a base for mounting other components. The backplate 15 can be made of materials such as metal or plastic, depending on the performance requirements, weight limitations, and cost considerations of the equipment. The light source wiring board 16 is responsible for connecting and distributing power to the first light element 8 and the second light element 9 in the equipment. The light source wiring board 16 includes multiple power sockets and switches, as well as related circuit protection and indicator elements. By properly designing the light source wiring board 16, stable power supply and flexible control of the light source can be ensured, thereby meeting different shooting needs. The cable chain 17 is a device used to protect and manage flexible pipelines such as cables and air hoses. In the imaging device, the cable chain 17 is mounted on the backplate 15, with one end fixed to the backplate 15 and the other end connected to the mounting plate 18 or other components that need to be moved or rotated. The cable chain 17 can freely extend, retract, and bend with the movement of the equipment, while maintaining the neatness and order of the internal pipelines, avoiding the risks of pipeline entanglement, wear, and damage. The mounting plate 18 is a structural component at the other end of the cable chain 17, used to mount various electronic components such as sensors, actuators, and controllers. The design of the mounting plate 18 should facilitate the disassembly and replacement of components, while ensuring they are stably fixed to the cable chain 17 and move with it. Through a well-designed mounting plate 18, the functionality of the equipment can be easily expanded, and its reliability and flexibility improved.

[0077] Optionally, when the imaging device is in single-projection mode, one projection component is provided and it is located on the side of the frame 1; when the imaging device is in dual-projection mode, it includes two projection components, both of which are fixed to the side of the frame 1 by the mounting base 5. The two projection components can be arranged symmetrically or adjacently, depending on the actual design requirements.

[0078] As an optional specific implementation, when the imaging device is applied to the field of 3D inspection, the side imaging component 6 is specifically a second camera component. The second camera component has a similar structure to the first camera component 2, or the first camera component 2 can be used directly to replace the second camera component. The second camera component does not need to be equipped with an adjustment ring, that is, when acquiring images from the side, it is not necessary to adjust the focal length between the camera body and the lens.

[0079] Meanwhile, for the scheme of mounting the second camera assembly on the side of frame 1, the specific structure of the mounting base 5 needs to be adapted to the installation of the second camera assembly. In this scheme, the mounting base 5 includes a horizontal plate, a vertical plate, and an inclined plate. The vertical plate is located on the lower side of the end of the horizontal plate near frame 1, and screw holes for connecting to frame 1 are opened on the vertical plate. The inclined plate is located in the middle of the upper part of the horizontal plate, and the side of the inclined plate relative to frame 1 is the mounting surface for mounting the second camera assembly.

[0080] In addition, the horizontal plate, vertical plate and inclined plate are preferably made in one piece to ensure the structural strength of the mounting base 5 to the greatest extent, thereby ensuring the stability and seismic performance of the second camera assembly installation.

[0081] In some embodiments, such as Figure 11 As shown, frame 1 includes a base plate 102, a first mounting member 103, and a second mounting member 104. The first mounting member 103 and the second mounting member 104 are spaced apart on the same side of the base plate 102. The first mounting member 103 is used to mount the camera body 201, and the second mounting member 104 is used to mount the lens 202. Both the first mounting member 103 and the second mounting member 104 have a plate-like structure. The spaced-apart arrangement of the first mounting member 103 and the second mounting member 104 on the same side of the base plate ensures a reasonable distance between the camera body 201 and the lens 202, and also makes the entire frame 1 more structurally balanced, reducing the risk of deformation due to uneven weight distribution. The base plate 102, the first mounting member 103, and the second mounting member 104 are manufactured using a one-piece molding process. This design not only enhances the overall structural strength of frame 1, enabling it to withstand greater installation loads, but also achieves a lightweight design. One-piece molding reduces the number of connection points between parts, lowering the risk of failure due to loose or ineffective connections, while also simplifying the assembly process and improving production efficiency. In addition, while ensuring structural strength, the frame 1 achieves a lightweight design through reasonable material selection and manufacturing processes (such as using lightweight and high-strength materials such as aluminum alloys). This helps to reduce the overall weight of the imaging device and improve portability and user comfort.

[0082] Meanwhile, the frame 1 also includes two reinforcing plates 105, which are respectively connected to the base plate 102, the first mounting member 103, and the second mounting member 104 on both sides. The main function of the reinforcing plates 105 is to further enhance the rigidity and stability of the frame 1 and prevent deformation or damage caused by external forces. The two reinforcing plates 105 are respectively set on both sides of the frame 1, connecting the base plate 102, the first mounting member 103, and the second mounting member 104. This not only enhances the lateral stability of the frame 1, but also reduces the stress on individual components by dispersing stress, thereby improving the overall durability of the frame 1.

[0083] In the design of frame 1, the reinforcing plate 105 can be integrally molded or installed separately, and each of these two methods has its own characteristics and applicable scenarios.

[0084] The integrally molded reinforcing plate 105 is connected to the base plate 102, the first mounting member 103, and the second mounting member 104 by continuous material to form a single structure. This design is more mechanically continuous, effectively transferring and dispersing stress, thereby improving the overall structural strength of the frame 1. Moreover, it is molded together with other parts of the frame 1 during manufacturing, reducing additional assembly steps and connection points, and improving production efficiency.

[0085] The separately installed reinforcing plate 105 can be independently designed and manufactured according to actual needs, facilitating adjustments to its position, shape, and size to adapt to different application scenarios. It is also more convenient when maintenance or replacement is required, as it can be disassembled and replaced individually without affecting other parts of the entire frame 1. In some cases, the separately installed reinforcing plate 105 may have a cost advantage due to differences in material selection, manufacturing, and assembly costs.

[0086] It is worth mentioning that, in order to further achieve a lightweight design, a hollow structure can be set on the reinforcing plate 105 as needed.

[0087] On the other hand, an optical detection device is also provided, which includes an imaging device, a driving device, and a moving device as described above, wherein the imaging device in the above embodiments is disposed on the moving device.

[0088] In optical inspection equipment, the imaging device is fixed on a moving device. The moving device, driven by a drive unit, moves the imaging device. In the scenario of inspecting circuit board defects, the moving device needs to move the imaging device to photograph the area to be tested on the circuit board. During this process, due to time constraints, the imaging device needs to move quickly and frequently, and quickly capture high-definition images after it is in position. If the positions of the first camera component 2 and the side imaging component 6 in the imaging device shift during or after the movement, the captured images will be blurry or inaccurate. In this solution, the installation stability and shock resistance of the first camera component 2 and the side imaging component 6 are optimized to ensure excellent shock resistance during movement. Even under conditions of rapid movement, frequent start-stop, and frequent shooting, the first camera component 2 and the side imaging component 6 can still be stably fixed in their corresponding positions on the frame 1 without displacement or shaking, thus ensuring that the acquired images have sufficient clarity and accuracy. This design not only improves inspection efficiency but also greatly enhances the reliability and durability of the equipment.
